Object to be checked for authenticity and a method for manufacturing the same
First Claim
1. An object to be checked for authenticity, comprising:
- a base material formed of paper containing a plurality of wood pulp fibers;
a plurality of fibrous magnetic polymer elements incorporated in the base material, together with the wood pulp fibers, each of the elements including an element main body formed of an acrylic resin and magnetic metal powder contained therein;
the wood pulp fibers and the magnetic polymer elements being tangled with one another in three dimensions;
a scanning region for checking the object for authenticity; and
a code indicator section for storing encoded information corresponding to an output obtained in accordance with the distribution of the magnetic polymer elements in the scanning region, said region and said section being located in said base material.

Abstract
A large number of magnetic polymer elements are distributed at random in a base material of a object to be checked. Each magnetic polymer element includes an element main body formed of a high-molecular material, such as an acrylic resin, and magnetic metal powder contained therein. The base material is formed mainly of paper, and the magnetic polymer elements are incorporated together with wood pulp fibers in the base material. The elements and the fibers are tangled with one another in three dimensions. Indication data including figures, symbols, etc., such as post position numbers and bet numbers on betting tickets for publicly-managed gambling, are printed on the object. The indication data, along with a proper output signal obtained in accordance with the state of distribution of the magnetic polymer elements, are enciphered according to specific rules for enciphering, and are recorded in a code indicator section by means of a recording medium, such as a magnetic stripe which is magnetically readable or a bar code which is optically readable.
